Need Some Help

[Silverback51]

I have done a search and was not able to find what I need. Maybe I just missed it, so here goes.

My SPF currently has Goodyear GT II's on it. 255/60-15 on the front, and 275/60-15's on the rear.

My ride height to the center of the wheel wells to the ground are 26.75 in the front, and 25.5 in the rear.

I ordered some Goodyear Billboards and they will be here next week. I know that I will have clearance problems in the rear, as the 275's have less than 1/2 inch space between the tire and body.

The current rear tires have a 27.9 inch diameter. The new BB's have a 26.7 diameter. This would give me a ride height of 24.9 inches. I have not seen anyone running that low that I could find.

Now to my question. For those that are running the Goodyear Billboards on their SPF, what is your ride height? Also, on your upper rear shock mount, what 2 holes is the bracket bolted to? If I remember right, for a stock SPF they utilize the bottom two holes. Mine is bolted to the center two holes. I think I will have to change this, but don't want to do it if it's not necessary.

And yes, I know I will have to have it aligned after all these changes.

Any input will be greatly appreciated.

Thanks

John
